Foldable electronic device

Abstract

A foldable electronic device includes a foldable casing, a flexible electronic element, and at least one roller. The flexible electronic element is disposed in the foldable casing, and the roller is correspondingly pivoted to a bending position of the foldable casing. The roller enables the flexible electronic element to slide and to be bent along the roller when being unfolded or folded together with the foldable casing, so as to avoid the generation of creases, such that the flexible electronic element is capable of serving as a display screen of the foldable electronic device.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 099214926 filed in Taiwan, R.O.C. on Aug. 4, 2010, the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of Invention[0003]The present invention relates to a foldable electronic device, and more particularly to a foldable electronic device with a flexible display as a display screen.[0004]2. Related Art[0005]In recent years, with the rapid development of technology and information, manufacturing technologies of electronic products are also improved gradually. In consideration of the pursuit of portability and practicability, the electronic products develop towards being light, thin, short, and small. For example, screens have developed from early large-volume and large-weight cathode ray tube (CRT) displays to light-weight and thin-volume liquid crystal display (LCD) displays. Moreover...

Benefits of technology

[0014]In the foldable electronic device according to the present invention, the flexible screen is capable of being unfolded or folded together with the foldable casing. However, when the flexible screen is bent, creases may be generated. Therefore, the foldable electronic device of the present invention has a roller, and the roller is disposed on a bearing to which the foldable casing is pivoted and is pressed against the flexible screen, and has a radius greater than the flexible radius of the flexible screen, such that the flexible screen is capable of being bent along the outer diameter of the roller and extending and sliding, thus no crease is generated on the flexible screen and no frictions and damages on the foldable casing occur. Therefore, the present invention solves the problems and applies the flexible display in the foldable electronic device to achieve the efficacy of having a minimal volume when being folded and having a maximal display screen when being unfolded.

Problems solved by technology

Moreover, due to the pursuit of small size of electronic products for convenient carrying, the size of displays gets smaller relatively.

However, common displays generally cannot have convenience in carrying and comfort in use at the same time, that is, when the screen gets smaller and can be easily carried, the area of the screen is reduced correspondingly, such that the content of the screen frame is reduced, and is inconvenient for the user for watching.

In order to solve this problem, foldable electronic screens are developed, that is, a plurality of small-size displays are combined into a large-size screen, but joints are generated between the displays, and thus the frame quality is deteriorated.

However, the flexible display has a requirement of minimal bending curvature when being rolled up, and due to excessive small curvature, the flexible display has a fold, and cannot display normally when being unfolded again, so the flexible screen cannot be rolled up to be excessively small.

Therefore, the conventional design cannot solve the problem, and the flexible display cannot be implemented on the current foldable electronic products.
